结构控震设计中流体阻尼器的指数选择与控制系统设计

参数选择作为流体阻尼器应用中的关键问题之一 ,目前尚未进行深入研究。以结构损伤和层间最大剪力为参考指标 ,对比了不同速度指数流体阻尼器的控震效果 ,发现流体阻尼器速度指数对实际控制效果影响很大 ,尤其表现在对结构损伤组成的影响和不同震级地震的适应能力方面。结合设计实践 ,给出了流体阻尼器参数选择的一般原则 ,并对流体阻尼器控制系统设计的一些问题进行了探讨。还对损伤理论和基于结构最大动反应的计算理论进行了对比 ,揭示了结构损伤理论在阻尼器参数选择中的良好作用

EXPONENT CHOICE OF VISCOUS LIQUID DAMPER AND DESIGN OF CONTROL SYSTEM IN DESIGN OF STRUCTURE CONTROL

Exponent choice,one of the key problems of the application of viscous liquid damper,has not been researched deeply today.This paper compares structure control effect of viscous liquid damper with different velocity exponents on the structure damage and shear force,and finds the velocity exponent has a great influence on effect of structure control,especially behaving in the makeup of structure damage and the adaptability of different earthquake magnitudes.Considering the practice of design,this paper puts forward the basic principle of viscous liquid damper choice,and gives some advices on the design of control system.This paper compares the damage theory to the calculation theory based on maximum dynamic responses of a structure,and opens out the well action of the structure damage theory on the exponent choose of viscous liquid damper.
